Which of the following accurately describes the role of tumor suppressor genes in cancer development?
a) Tumor suppressor genes promote cell division and growth, and mutations that activate these genes can lead to uncontrolled cell proliferation.
b) Tumor suppressor genes inhibit cell division and growth, and mutations that inactivate these genes can lead to uncontrolled cell proliferation.
c) Tumor suppressor genes are involved in DNA repair and apoptosis, and mutations that activate these genes can lead to uncontrolled cell proliferation.
d) Tumor suppressor genes are involved in the activation of oncogenes, and mutations that inactivate these genes can lead to uncontrolled cell proliferation.
